dzl2 10kg pressure 2 ton coal steam boiler
Coal-fired dzl2 10kg pressure 2 ton coal steam boiler scale can cause harm and failure scale is the first coal-fired steam boilers, coal-fired steam boiler is the main cause of the accident, the danger main problems: wasting a lot of fuel: Because the thermal conductivity of the scale of only a few steel one tenth, so that the heating surface when the fouling of heat transfer will hindered, in order to maintain a coal-fired steam output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now can be used efficient and environmentally non-corrosive cleaning agent fired steam cleaning, expose the metal tube so that the device primaries, and to reduce biological fouling of algae because silt impact. While the peeling effect of iron on the iron oxide and ethylene, prolong the service life of coal-fired steam boilers, to reduce energy consumption and improve productivity. Fired steam after a long run, the inevitable emergence of scale, the problem of corrosion, scale coal-fired steam boiler formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation, the coal-fired steam furnace with a series of physical, chemical, and finally heating surface to form a hard, dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, leads to a reduction endothermic coal-fired steam boiler waterwall furnace, burning coal steam boiler furnace exit temperature increases, the increase in the loss of coal-fired steam boilers. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of coal-fired steam boilers.
Check Item item hot water boiler hot water boiler comprising a boiler inspection and checking internal use preparations, checking in the furnace and the flue, the boiler attachment check, check automatic control system, the secondary device, check the combustion device, the auxiliary heat check the surface of the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect and causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling. It is fed out of the hot water boiler heat equivalent to a mass per hour (usually expressed in tons) in water was heated from 20 ℃ and heat output of all vaporized into a dzl2 10kg pressure 2 ton coal steam boiler water absorbed three expressions, in tons) water from 20 ℃ heated and vaporized into all heat absorbed by the steam boiler it is fed out of the hot water heat equivalent to a mass per hour (i.e. typically kcal / hr (kcal / h), tonnes / hour (t / h ), megawatt (MW). (1) kcal / h is in metric units of expression, which represents the heat of hot water boiler fed out per hour. (2) t t borrowed steamed steam boiler popular argument, ( 3) megawatts (MW) is the international system of units unit of power, the basic unit is W (1MW = 106W). this expression formal documents should be used.
How many calories Horizontal one ton dzl2 10kg pressure 2 ton coal steam boiler needs? 1 ton steam boiler, require 600,000 calories, biomass is the most economical fuel. 1 t of steam boilers, 600,000 calories needed, is converted into fuels: diesel 58kg / hour, i.e. cost of diesel and 466 / hour; biomass particles 150kg / hour, the cost of 165 / hour. 697 electrical degrees / hour, i.e. cost of electricity 697 / hour; gas 75m3 / hour, i.e. cost of natural gas 375 / hour; 120kg of coal / hour, i.e. cost of coal is about $ 120. As can be seen from the above, coal and biomass particles are the most economical. Wherein the combustion of coal is difficult to control, and the actual consumption costs considerably biomass particles. However, polluting coal boiler is very large, and the biomass boiler is both economical, and environmentally friendly. Accordingly, we can see that biomass pellet boiler is the best future direction of development of the industry boiler, the boiler will also become the industry mainstream.
Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green boiler heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.
